Title: Electronic web timer for web transport systems
IPC: G11B27/13
Filed: 1969-09-29
Abstract: 1,235,956. Tape counter. AMPEX CORP. 29 Sept., 1969 [13 Dec., 1968], No. 47701/69. Headings G4H and G5R. An electrical counter for a magnetic video tape (or other web-form record) produces binary signals indicating the position of the tape and decodes and displays these signals. Pulses corresponding to tape movement may be produced by a tachometer 31 coupled to the tape drive, or by a transducer (14, Fig. 4, not shown) monitoring control pulses on the tape, or by an address process unit 37 if the tape carries an address track. A divider 32 produces one pulse per frame or per second of tape running time. These pulses are then counted by a " clock " 36 (also Fig. 3, not shown) whose binary output is decoded at 38 and displayed on at least one display 40 in terms of elapsed hours, minutes, seconds and frames. A direction sensor 33 controls the clock direction, and ensures that when the tape is reversed the divider 32 produces pulses at the same points on the tape as in the forward direction. If a tachometer is used, a standard selector 34 controls the divider 32 according to the preselected tape speed and number of frames per second. If an address process unit 37 is used and has a binary output, the clock 36 is not used. For editing purposes a selection switch assembly 48 is provided which can be set to produce a binary code output indicating a desired stop time. This output is compared with the binary clock output in a comparator 46, and a coincidence signal may control the tape transport or other system.

A headlamp for a vehicle having a streamlined body comprises a symmetrical reflector 1, a spacing element 3 of non-vitreous material which is applied against the first edge of the reflector, e.g. by engaging a rear flange 5 on the spacer in a groove 6 in the reflector and a relatively thin glass wall 4 mounted on the spacer, e.g. by engaging the rear edge 4 of the glass in a groove 7 of the spacer. The spacer may be made of metal, e.g. light alloy, or of plastics material and the inner surface can be metallized to serve as a reflector. The glass wall may be grooved in known manner to provide the desired distribution of light. In a modification the spacer is made of transparent plastics material and has a solid front wall, the inner surface of which is grooved, and the thin glass wall is secured within a recess in the outer surface of said solid front wall.

Abstract: 1465128 Opening containers; packages ROBERT BOSCH GmbH 5 Nov 1974 [7 Nov 1973] 47870/74 Headings B8D and B8C A wall (e.g. a lid) of a sealed container comprises a metal outer layer 11 and a plastics inner layer 13 having a tear-open area 29, which is defined by one or more weakening lines (e.g. scores) 20 and 21 and which has a start section by one or more graspable tongues 27 and 28 punched-out of the wall, and a plate 35 which is heat-welded to the plastics inner layer beneath the tongue or tongues along an endless continuous weld seam 36 to seal the container. As shown, tongues 27 and 28 are provided at the corner of the lid 11, which is heat-sealed to a deep-drawn like laminated container body, and are each associated with a respective one of two portions of a tear-open area divided by a diagonal scoreline 21. The configuration of the weld seam defines an apex 37 or 38 located at the base of each tongue and printing in the direction of tearing to minimize the opening forces necessary to break the seam. The plate may be wholly of plastics, Fig. 7 (not shown), or comprise an outer plastics layer 40 and a metal inner layer. The inner metal layer may be covered by an internal plastics foil 42 heat-sealed to the lid, Fig. 9 (not shown). Alternatively, the plate may comprise a metal layer 44 sandwiched between plastics layers 43 and 45, Fig. 8 (not shown), the edges of the latter being joined together, on welding of the plate to the body, to encapsulate the metal layer. In a modified embodiment of Fig. 5 (not shown), the weakening line 21 is replaced by oppositely curved weakening lines 45 and 46 in a rectangular lid and the plate is additionally welded to the underside of the lid by auxiliary welds 39 extending parallel to the ends of the weakening lines 20, 45 and 46 at the base of the tongue. In another embodiment, weakening lines 47, 48 and 49 define similar tear-out portions, the weakening lines 47 and 48 each initially diverging away from each in a direction away from the tongue. In another embodiment, Fig. 10 (not shown), the tear-open section is of teardrop configuration and is defined by a centrallylocated semicircular tongue 67 and convergent weakening lines 64 and 65. In a final embodiment, Fig. 12 (not shown), a tongue 75 is joined by arcuate lines of weakness 78 and 80 to a peripheral line of weakness 79 and the weld apex 82 is directed towards the free end of the tongue. The plastics of the lid and body may be polypropylene and the plastics material of the plate may be a copolymer of propylene so that a sufficient, but not excessively strong, weld-seam 36 is formed.

A self-levelling lifting spreader comprises a beam 13, Fig. 1, supported from a crane hook 8 by cables 5, 6 and runners 3, 4 which are held apart by hydraulic rams 9, 11 and 10, 12. The cylinders 11, 12 of the rams are connected through valves V1, V2, to an hydraulic accumulator H. If the centre of gravity of the load L is offset as at W, the higher pressure in the cylinder 11 as the load is raised opens the valve V2 and allows fluid to pass from the cylinder 12 to the accumulator until the pressure in the two cylinders is equalized. As this occurs the runner 4 moves inwards until the point W is vertically below the hook 8. Figs. 3, 5 and 6 show embodiments with two, three and four rams respectively, the mode of operation being similar in each case.

Abstract: 1365713 Sewing apparatus TAKATORI MACHINERY WORKS Ltd 10 Nov 1971 [19 Nov 1970] 52108/71 Heading D1G [Also in Division A3] Special machines (Fig. 1C) Panty hose are made by positioning hip length stockings 1, 2 as shown, clamping them together along lines 3, 4, cutting the clamped inside surfaces of the stockings between the lines 3, 4, rotating the clamps to present the cut edges outwards, stitching along the lines 3a 3b to join the stockings to form the panty hose and removing the completed article.  Feed by clamps (Figs. 3, 4B) The apparatus provided comprises a carrier 7 moved along a circular pathway by a motor 10 and gearing 9, 8. Mounted on the carriage are a number of clamping units each comprising two sets of clamps, e.g. 25a, 25b, each set being carried on a respective arm 18, 17 connected to rotate from the position shown at stations B and F to the position shown at C, &c, when gearing 15, 16, 23a, 23b, 24, 24a is engaged by stationary racks 26a 26b &c as the carrier 7 moves along its tracks. Each pair of clamps is urged open by a spring (68a, Fig. 10A not shown) and selectively closed by an electromagnet (62a) to grip the stockings when required. A pair of stockings are loaded on the clamp units at A, the carrier moves to station B where a pneumatically operated cutter 27 cuts the stockings between the clamp lines, to station C where racks 26a &c swing the arms 17, 18 apart to present the cut portion in a substantially straight line to be sewn, at station D, by the sewing machine 29a. At station F, after the arms have swung together again and the clamps released, a solenoid operated clamp (47, 48 Fig. 9A not shown) grips the legs of the panty hose, which extend over a plate 46 and a pneumatic cam (50) moves the clamp outwards to remove the completed article from the clamp assembly. On approaching station A a stationary cam 31 engages a follower 30 on the clamp assembly to swing the latter through 45 to present the clamps at a suitable angle for loading the next pair of stockings. Cutting work The knife 28 is extended by a pneumatic cylinder 27 pivoted at the centre of the machine so as to move with the clamp assembly while being extended to cut the work. To this end a lever (40, Fig. 8B not shown) mounted on the pivoted cutter assembly is rocked by a solenoid, as the clamp assembly reaches station B, to engage a stop of the clamp assembly and cause the cutter assembly to move round with the former. After severing the knife is withdrawn and the solenoid deenergised to allow the cutter assembly to be returned by spring 43b against the action of damper 44. Use of Air In addition to the pneumatic operation of cutter and unloader a suction nozzle 29b is located just upstream of the sewing machine 29a to tension the cut edge during the sewing. In a further embodiment (Fig. 11 not shown) the two clamps are interconnected by links and are reciprocated along a linear path (76) by a chain (74) the clamps are swung apart, when required, by arms (82, 84) having rollers (86, 87) engaging a cam track (88).
